"'Leave only footprints' may be the outdoor industry ethos, but Greenpeace says a study it recently conducted revealed troubling indications that the apparel made for outdoor recreation contains persistent chemicals, some of which are linked to negative health effects in both humans and animals."

"For the study, Greenpeace commissioned two independent labs to analyze the waterproofing membranes applied to 14 different jackets and pants, which the organization purchased from a wide range of manufacturers, including The North Face, Marmot, Patagonia, and a number of companies popular in Europe, including Mammut and Jack Wolfskin. Greenpeace says the report highlights the need to ban PFCs from textile manufacturing."
